Triangle Orthopaedics Surgery Center

Michael K. Merz, a board-certified Orthopedic Surgeon for our EmergeOrtho—Triangle Region Sports Medicine Team, specializes in Hip and Knee Preservation and Replacement. His extensive training under some of the nation’s leading hip experts has allowed Dr. Merz to help countless patients recover from conditions such as hip dysplasia (DDH), femoroacetabular impingement (FAI) or hip impingement, hip labral tears, Perthes disease, avascular necrosis (AVN) of the hip, femoral anteversion, congenital hip dislocation, and more.

Education and Expertise

Dr. Merz graduated magna cum laude with a Bachelor of Science degree at Baylor University before attending medical school at the University of Texas Health Science Center in San Antonio. After finishing medical school, he completed an orthopedic surgery residency at the University of Illinois in Chicago. In his final year of residency, he served as the administrative chief resident.

Dr. Merz completed two fellowships after residency—adult reconstruction and hip preservation. He was an Otto E. Aufranc fellow in adult reconstruction at New England Baptist Hospital in Boston, MA. While there, he had extensive training in primary and revision total hip and knee surgeries as well as partial knee replacement.

Due to his specific interest in the hip, Dr. Merz completed a second fellowship in hip-preserving surgery at Boston Children’s Hospital, affiliated with Harvard Medical School. He underwent comprehensive training with leaders in the field for patients with hip conditions, from birth through middle age. This included both arthroscopy and osteotomies of the pelvis and femur.

Specific conditions addressed by Dr. Merz include:

  • Hip dysplasia (DDH)
  • Femoroacetabular impingement (FAI)
  • Hip labral tears
  • Perthes disease
  • Avascular necrosis (AVN) of the hip
  • Femoral anteversion
  • Congenital hip dislocation

Dr. Merz also has a great interest and passion for preventing arthritis of the hip joint through hip preservation. When treating patients, he offers a comprehensive approach that involves patients in the discussion of the risks and benefits associated with surgical versus nonsurgical treatment. When surgery is required, he incorporates minimally-invasive techniques to reduce discomfort and improve recovery time.

In addition to addressing conditions of the hip, Dr. Merz also treats knee issues and other general orthopedic problems utilizing the following methods:

  • Hip arthroscopy
  • Bernese periacetabular osteotomy (PAO)
  • Revision hip and knee replacement
  • Proximal femoral osteotomies
  • Fracture care of the hip, knee, and pelvis

Dr. Merz sees patients of all ages and operates primarily at North Carolina Specialty Hospital, Triangle Orthopaedic Surgery Center, and Duke Regional Hospital.

I have been dealing with a job injury for two years. Finally saw Dr. Merz as a second opinion, and he has squared me away without a hitch. Just now ready to start physical therapy after surgery. Dr. Merz’s office staff is also an absolute joy to work with from check in, to check out.
